The role of nonmagnetic d0 vs. d10 B-type cations on the magnetic exchange interactions in osmium double perovskites

“…Investigations into double perovskites with single Os 5+ magnetic sublattice will provide help for a better understanding of the remarkable magnetic properties of osmium double perovskites, such as the exceptionally high-temperature ferrimagnetism in Sr 2 CrOsO 6 [2] and the strikingly different magnetic properties between Sr 2 FeOsO 6 [12,13] and Ca 2 FeOsO 6 [3,7]. Most of the well-studied double perovskites with nonmagnetic B cations and Os 5+ forming the B′ sublattice known so far display AFM transitions [16][17][18][19][20][21][22][23].…”

“…Double perovskite oxides, A 2 BB′O 6 , containing 4d/5d elements have attracted considerable attention due to their remarkable electronic and magnetic properties, such as room-temperature magnetoresistance [1], high-temperature ferrimagnetism [2,3], as well as spin glass [4] and valence bond glass behaviors [5]. As a characteristic structural feature, there are interpenetrating B and B′ face-centered cubic (fcc) sublattices, and their complex magnetic properties are determined by the intricate interplay between the geometrically frustrated intra-sublattice and inter-sublattices exchange interactions, which are correlated with structure distortions [6][7][8][9][10][11].…”

Crystal Structure and Magnetic Properties of Sr2LiOsO6

“…In recent years, 5d oxides have received considerable attention because of their distinctive features such as unusual superconductivity in KOs 2 O 6 [1], noticeable metal-to-insulator transition in NaOsO 3 [2], unusual Mott-insulating state in Sr 2 IrO 4 [3], and unusually high Curie temperature of ~725 K in Sr 2 CrOsO 6 [4]. In particular, osmium-containing oxides have been investigated intensively, and recently, the structure and magnetic properties of Ba 2 MOsO 6 (M = Li, Na, Ca) [5,6], Sr 2 MOsO 6 (M = Fe and Cr) [4,7], and Ca 3 OsO 6 [8] have been studied.…”

We synthesized Sr 2 LiOsO 6 to search for a 5d feature that is distinguishable from 3d features.…”

Interplay between lattice distortion and spin-orbit coupling in double perovskites

“…1,2 One class of such frustrated antiferromagnets is found in the double perovskite oxides, which host a wide range of interesting behavior. [3][4][5][6][7][8] These compounds of chemical formula A 2 BB ′ O 6 feature ordered, interpenetrating facecentered cubic (FCC) lattices of the B and B ′ ions when the charge difference between these ions is large. 9 Both B and B ′ transition metal ions are octahedrally coordinated by oxygen.…”
